// .NAME vtkWorldPointPicker - find world x,y,z corresponding to display x,y,z
|
|
// .SECTION Description
|
|
// vtkWorldPointPicker is used to find the x,y,z world coordinate of a
|
|
// screen x,y,z. This picker cannot pick actors and/or mappers, it
|
|
// simply determines an x-y-z coordinate in world space. (It will always
|
|
// return a x-y-z, even if the selection point is not over a prop/actor.)
|
|
|
|
// .SECTION Caveats
|
|
// The PickMethod() is not invoked, but StartPickMethod() and EndPickMethod()
|
|
// are.
